[MMC] Give the MMC host the full-sized request.

Pass the total number of MMC data blocks in the request to the
host driver.  Since existing MMC host drivers do not support
scatter-gather at present, the block queue defaults have been
chosen to prevent scatter-gather block requests for MMC.  A
host can alter these parameters when it wishes to take advantage
of SG capabilities.
